I truly believe it's here to stay. I'm proud we were the guinea pig.
We're a little bit of a guinea pig, but I think that's great. The sport has been hurt by the fact there are so many factions. We're all pitching in together. It's a great day for tennis.
We're the guinea pig, which we're happy to do. I've got to believe the players are going to love this. You'd like to have a situation where you're not going to lose a tennis match because of a bad call.
